The present invention provides a method and a gaseous composition for bioremediation of soil and groundwater contaminated with organic compounds, including halogenated organic compounds and explosives. The gaseous composition contains (a) at least one gaseous microbial metabolic inducer and (b) a carrier gas. The gaseous composition may also optionally include one or more of a gas phase nutrient, a gaseous carbon source, a gas phase reductant, and a moisture source.
La présente invention porte sur un procédé et sur une composition gazeuse utiles dans la biorestauration du sol et de l'eau souterraine contaminés par des composés organiques, tels que des composés organiques halogénés et des explosifs. La composition gazeuse renferme (a) au moins un inducteur métabolique microbien gazeux et (b) un gaz vecteur. La composition gazeuse peut également comprendre, éventuellement, au moins un des éléments suivants: une substance nutritive en phase gazeuse, une source de carbone gazeux, un agent réducteur en phase gazeuse et une source d'humidité.
